Hungarian architect. He became a leading member of the Modern Movement between the wars. At the Bauhaus he designed his Red Cube House (1922) which was to be published, and is associated with Hungarian Activism. In 1929, at the invitation of Gropius, he contributed to the CIAM conference on ‘The Small Apartment’, after which he and others formed the Hungarian branch of CIAM. A powerful protagonist of International Modernism, Molnár designed several white-rendered blocky houses, with bold cantilevers and deep terraces, set in the hills around Budapest, clearly influenced by De Stijl. Some of his designs (e.g. Houses on Cserje (1931) and Lejtö (1932) Streets, Budapest) are paradigms of the International Style that gelled at the Weissenhofsiedlung, Stuttgart, in 1927. His Budapest apartment-blocks on Lotz Károly Street (1933) and Pasaréti Avenue (1937) are also significant. For a brief period in 1933 he collaborated with Breuer before the latter emigrated to America. Molnár was killed during the Soviet siege of Budapest (1945).
